RAEN MCP Gateway — for MCP client users

Five production tools over the Model Context Protocol. Your first call on each is free. Get a working Bearer key by email in under 3 minutes — no sales call, no signup wall.

The tools

Tool	What it does	Price / call
`raen_law_lookup`	Statute lookup across RAEN's law-pages corpus (36 consumer-law statutes)	$0.05
`raen_ticker_analysis`	Multi-agent equity consensus (TradingAgents pipeline)	$0.05
`raen_dispute_letter`	FDCPA/FCRA-compliant dispute letters with citations	$0.75
`raen_image_generate`	Image generation (Gemini-backed)	$0.01
`raen_contract_analysis`	Contract risk analysis with clause findings	$0.05

Connect in 3 steps

Step 1 — get a dev key. One POST, no account:

curl -X POST https://raen-mcp-gateway.fly.dev/keys/request \
  -H 'Content-Type: application/json' \
  -d '{"email":"you@example.com"}'

You'll receive a verification link by email; your 30-day Bearer key is issued after you click it. Rate limit: 3 requests/day/IP.

Step 2 — point your MCP client at the gateway. Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "raen": {
      "command": "npx",
      "args": ["-y", "mcp-remote",
               "https://raen-mcp-gateway.fly.dev/mcp",
               "--header", "Authorization: Bearer YOUR_KEY"]
    }
  }
}

Cursor / any Streamable-HTTP client: same URL https://raen-mcp-gateway.fly.dev/mcp with Authorization: Bearer YOUR_KEY.

Step 3 — first call is free. Invoke any tool from your client. Each tool's first call runs the free-first-call flow (charge-and-rebate on-chain via x402 on Base — you pay USDC and are rebated the same amount the first time). After that, per-call pricing above, settled on-chain in USDC.
